Question

When a bow is shot,it has kinetic enegy fron where does it gets that energy?

Answer 1

We know K = 1/2 mv^2

So for kinetic energy u only require mass and velocity

The biw u thrown must be having a certain mass

And as it is thrown it will have some velocity.

Hence it gets the kinetic energy.

Answer 2

your answer

kinetic energy depends on mass and square of velocity of the body so as the speed increases of heavy body ke will be more and vice versa

hope helps
